CAP FOR THETIIPS F UMBRELLA RIBS.

Application filed February 7, 1922. Serial No. 534,678.

To all whom it may concern.

Be it known that I, SAMUEL S. Fnnrz, Sn,

a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a newand useful Cap for the Tips of Umbrella Ribs, of which the following is a specification.

My invention consists of a cap appliable to the tip of the rib of an umbrella (or parasol) the same being seamless and plated and being swedged on the rib, the cap thus being water and rust proof as well as adding its ornamental nature to the rib and being held firmly and securely on the latter.

The invention is satisfactorilyillustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specifiotdetails shown and described, as long as they are within the spirit or scope of the claims.

Figures 1 and 2 represent side elevations at a right angle to each other of a cap for the tip of an umbrella rib embodying my invention. Figure 3 represents a longitudinal section thereof on line 33 Figure 2.

Figure 1 represents a transverse section on line 4-4: Figure 1.

Figure 5 represents a diametrical section of the cap in normal condition.

Figure 6 represents a similar section there of in swedged condition.

Similar numerals of reference indicate corresponding parts in the figures. Referring to the drawings,

1 designates the rib of an umbrella, the same being approximately U-shape in longitudinal direction and japanned, the outer end or tip portion 2 thereof being compressed together and thus reduced and fiattened in cross section all as well known.

3 designates a cap which is appliable to said outer end or tip portion 2 of the rib,

it being formed of a hollow body of metal primarily of a cylindrical side 4 and convex crown 5 as shown in Figure 5, said body being fitted on the said end portion 2 of the rib, and the inner rim edge 6 of its side near said edge being swedged inwardly forming a reduced neck which is pressed tightly againstthe portion 2 ofthe rib and thus being'firmly connected with said portion and consequently with the rib forming a water tight joint therewith, the body of the cap being converted into spherical form as shown in Figure 6 and likewise in Figures 1, 2, 3, and 4, and being integral and likewise seamless in its nature.

The cap is plated and so it is water and rust proof whereby its life is vastly prolonged.

Attention is directed to the fact that thev rim edge of the cap is in a measure flattened and so converted from a cylindrical form into one comparatively oblong in cross section in which condition it embraces tightly the reduced or contracted portion 2 of the rib and so is held thereon whereby it is prevented from turning thereon and outwardly disengaging therefrom.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

l. A cap appliable to the flattened tip portion of an umbrella rib consisting of a hollow body adapted to receive said portion and a cylindrical open-ended portion having its inner rim edge adapted to be compressed tightly upon said flattened tip portion.

2. A'cap appliable to the flattened tip portion of an umbrella rib consisting of a hollow body of spherical form, and a rim edge of comparatively oblong form adapted to be compressed seamless and water tight about a tip portion of an umbrella rib.

3. A cap applicable to the flattened tip portion of an umbrella rib consisting of a hollow body adapted to receive said portion and having its inner rim edge adapted to be compressed tightly upon said flattened tip portion to form a water tight joint said cap being seamless and having a plating of water and rust proofmaterial. I

4. A cap appliable to the flattened tip portion. of an umbrella rib consisting of a hollow body of spherical form, and a rim edge with reduced neck ofv comparatively oblong form to'insure a water tight joint, said cap being seamless and having a plating of water and rust proof material.
